[Digital and electromagnetically controlled pinchers for spinal cord injury].
A kind of noval digital and electromagnetically controlled pinchers is developed from its original type for more quantitatively pinching the spinal cord. The instrument is designed based on electromagnetic theory and principle of equilibrium in mechanics and composed of a timer, a current regulator and meter, control circuits and two-arm pinchers. The interarm distance, the pinch force, duration, and direction of left and/or right arm can be set up and adjusted. The current flowing through one or two pinching arms can be displayed and hold digitally on a screen. The machine is characterized not only by its convenience and correctness in operation but also by its directness and accuracy in reading. The setup is applicable to produce different kind and extent of spinal cord injury in many species of animals.
